Well finally got around to getting some pictures of the nitron 1 coilover kit that I have had fitted!
The quality is fantastic and Spire did a great job of fitting and setting up the car. I will take some pictures of the car with the wheels on but I am just waiting on my Eibach hub centric spacers being delivered! I have gone for 20mm front and 12 mm rear! Should look good on completion.

drool!! congrats OP - should be night and day on the track... what spring rates did you get and what are your camber settings?

I have left the set up details in the car which is at work but will post on monday! Spire who fitted the kit set the car up for fast road and as I paid nothing for it thought best not to request to much as all I needed to do was loan them my car for a few weeks!

The ride feels naturally firmer but not teeth shattering! I was concerned that it would ruin the ride but really pleased to say that the ride is great! The biggest change for me is the way the cars steering feels as made it so precise!
the track day on Monday will really make me see just how good the car is!

Sorry to pull a old thread back up but how did you get on eventually? I know the cars been sold but am looking for coilovers and can't decide.
Mind was set on kw cs but they don't fit my new wheels so trying to find another.

I spoke to Nitron and their kits require rebuilds far too frequently for my liking. I do not recall the exact frequency right now but it was ridiculous unless you were set up like a race team.

From discussions with KW & Bilstein plus feedback from owners that have run them, I'll be going with TC Kline DA coilover kit. I like what they have done for the M3, their road & track testing is 1st class as are customer reviews. Also I expect it to be lightweight given the aluminium shocks and lighweight custom Swift springs. I'm trying to get a comparison to stock.

Hi,

I'm in London and am also looking to upgrade my suspension.

Have been looking at various options and am leaning towards Ohlins Road and Track but having seen your post I have researched the TC Kline kit and that looks good too.

Where would you be buying it from (is there a UK dealer) and where would you get it fitted?

Cheers for that info about th nitrons,
Not looked into the tk line too much but really wanted the kw clubsports

Will have a look into them but the ohlins dfv and Jrz rs1 look good but the Jrz would be a pain to get rebuild or fixed as American based.

I buy it from Harold and team at HP Autowerks or TC Kline directly in the US. Would advise speaking with them to discuss your specific requirements so that you choose the correct springs and suspension settings; one road and one for track.

All my work is done at PMW in Chelmsford Jack. After your rear sub frame job taking so long, I'd recommend you speak to Daniel (manager) or Peter the owner. Both know the M3 inside out.

Well, if they haven't done an E92 yet they may find it takes a little longer. Anyway, I would recommend doing the diff and subframe bushings although the benefits are not massive they are still worthwhile.

I was considering Nitrons as well till I read this. I wonder what their rebuild frequency is.

The other options are KW CS which is overkill for me and not sure how they'll do everyday driving with the potholes we have. Then there is Ohlins as well.
